PURPOSE: A video code capable of real-time processing is provided to enable real-time process to data input from a camera with independently processing own assigned function in a main processor and a co-processor. CONSTITUTION: A video capture part(12) converts an analog image signal photographed by a camera(11) into a digital image signal, and thereafter converts the digital signal into data format appropriate for video codec processing. A C.M.(Common Memory) part(13) receives data outputted from the video capture part(12) and stores data. A main processor(14) reads necessary data from the C.M. part(13) for storing data in an L.M.(Local Memory) part(15) or temporarily storing data in an inner memory part of a DSP, and transmits data required by a co-processor(16) for processing the assigned function to the first IPC(Inter Processor Communication Module). The first IPC stores input data. The co-processor(16) reads necessary data from the first IPC for processing the assigned function and outputs data related to the processed result to the second IPC. The second IPC stores input data. The co-processor(16) outputs a process completion signal to the main processor(14). The main processor(14) processes own function independent of the co-processor(16), recognizes that the co-processor(16) processes the own assigned function if receiving the process completion signal from the co-processor(16), and reads data stored in the second IPC for processing the other function independent of the co-processor(16).
